The latest build of Chimera demonstrates a highly experimental
implementation of Quartz rendering. The current build locks you
into Quartz, but the Quickdraw renderer will still be available
via a pref in a later point release. For now you're locked into
Quartz with the current build. Also, printing with Quartz turned on
is pretty busted, so don't even bother. :)

Chimera 0.2.0 has much improved scrolling over previous versions.
Most importantly it now uses native Aqua scrollbars rather than
emulating the look via the Appearance Manager. Scrolling is also
much faster, using both the wheel and the keyboard.

The tab browser feature has had some crash fixes and speed
enhancements. You can now also cycle through tabs via the keyboard
and close tabs. In addition the tab strip will auto-hide when only
one tab is being used.

Support for Command and Shift clicking of links has been added. You
can use Command+Click to open a link in a new window. If you use the
Shift modifier, the window will load in the background. You can also
make Command/Shift open tabs instead by setting the same pref that is
used by Mozilla. The load links in background pref that Mozilla uses
is also supported by Chimera. (These prefs aren't exposed in Chimera's
UI yet, so you'll have to enter your secret .mozilla dir and edit your
prefs.js by hand.)

Chimera 0.2.0 has a new splash screen, application icon, and new toolbar
and sidebar icons.

Finally and most importantly Chimera has had many crash fixes and
stability fixes.

Enjoy!

Building Chimera

Chimera has complete build instructions on mozilla's Web pages (under
the code name ChimChim). You can find those instructions
here.
Be aware that the downloadable build listed above contains numerous
patches to Mozilla that have not yet been accepted, so any builds that
you do will not be as stable or as performant as the downloadable
build above.

If you have questions about building, use the chimera mailing list or hop on to #mozilla, and someone can help you out.
